Patent number: 10087922Abstract: A four-compression-chamber diaphragm pump with multiple effects includes an eccentric roundel mount with four cylindrical eccentric roundels, a pump head body with four operating holes, and a diaphragm membrane with four annular positioning protrusions. A basic curved groove or other vibration-reducing first positioning structure is circumferentially disposed around each operating hole while a basic curved protrusion or other second vibration-reducing second positioning structure is provided in the diaphragm membrane for suitably coupling with the corresponding groove or other first positioning structure upon assembly, resulting in a shortened length of moment arm from the basic curved protrusions or other vibration-reducing positioning structures to respective downwardly-extending annular positioning protrusions in the diaphragm membrane, and consequently reduced vibration noise and resonant shaking in comparison with a conventional four-compressing-chamber diaphragm pump.Type: GrantFiled: May 18, 2015Date of Patent: October 2, 2018Inventors: Ying Lin Cai, Chao Fou Hsu

Patent number: 10082146Abstract: A blower is designed such that a backflow of air from a ventilation path into a cooling-air exhaust path is prevented by a fan-side rib and an electric motor casing-side rib. The electric motor casing-side rib is formed on an external side of the fan in a fan radial direction such that a distance between the fan-side rib and the electric motor casing-side rib in the fan radial direction becomes long. Accordingly, a flow of an electric-motor cooling air is less disturbed, and the electric-motor cooling air can be secured sufficiently. As a result, an electric motor can be cooled sufficiently, an abrasion of a brush is restricted, and a copper powder of a material making the brush is prevented from flowing into the ventilation path with the electric-motor cooling air.Type: GrantFiled: May 22, 2014Date of Patent: September 25, 2018Assignee: DENSO CORPORATIONInventor: Souta Okabe
